About 03NP4ZZ
03NP4ZZ is the ICD-10-PCS code for a release procedure on the right vertebral artery using a percutaneous endoscopic approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.
In plain terms, this corresponds to Freeing of vessel, the ICD-9-CM procedure title it maps to (39.91).
For a different body part, codes include 03N04ZZ (right internal mammary artery), 03N14ZZ (left internal mammary artery), 03N24ZZ (innominate artery), 03N34ZZ (right subclavian artery), 03N44ZZ (left subclavian artery), 03N54ZZ (right axillary artery) and 23 more.
The same procedure with a different approach is coded 03NP0ZZ (open) and 03NP3ZZ (percutaneous).
It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
